Application s lmh 25, 1939, Serial No. 264,175 1 laim. I (01. 308-89)The present invention relates generally to railway rolling stockequipment, and more particularly to a wiper for cooperating with ajournal of a car.

6 Due to the inherent nature of the construction of railway car journalboxes, it is impossible, to keep dirt, grit, sand, and the like, fromsifting into them. The oiled waste, or the like, within a boxperforms anoil wiping action, but it in no wise .eliminates the foreign matterwhich enters the journal box. Therefore. the foreign substances workbetween the journal brass and the journal, causing friction whichmarsthe moving parts and which ultimate y effects a hot box. Further,the waste itself works between the brass and journal. Hot boxes annuallytake a heavy toll in labor and money, yet, prior to the development ofthe present invention; nothing was in use on the rolling stock of therailroads to 20 satisfactorily prevent hot boxes.

It is, therefore, an object of the present invention to provide ajournal wiper which eflectively eliminates hot boxes caused by foreignsubstances,

waste, and'the like, getting between the journal 25 brassand journal ofa railway car.

Another object of the present invention is to provide a journal wiperwhich is adapted to keep the journal clean and free from foreignsubstances.

Another object is to provide a journal wiper which is adapted to bedisposed between a journal brass and a journal wedge, and to contact thejournal along two longitudinal lines.

Another object is to provide a journal wiper which .is adapted tocontact the Journal along longitudinal lines, to clean foreignsubstances, yet to permit the passage of a sufllcient amount oflubricant.

Another object is to provide a journal wiper of spring sheet metal whichcontacts the journal throughout substantially the full length thereof toremove foreign substances, and to permit the passage of a sufllcientquantity of lubricant.

Another object is to provide -a journal wiper which is inexpensive andsimple, yet thoroughly eilicient to fulfill all of the objects andadvantages sought therefor.

Other objects and advantages will be apparent 50 from the followingdescription, taken in conjunction with the accompanying drawing inwhich:

Fig. l is a plan view of a journal wiper constructed in accordance withthe teachings of the present invention;

Fig. 2 is a side elevation of the journal wiper shown in Fig. 1; a

Fig. 3 is a section on the line 3-3 of Fig. 2;

Fig. 4 is a longitudinal section through a journal box showing anembodiment of the present invention in operative disposition relativeto, a journal, a journal brass, and a-journal wedge; and,

Fig. 5 isa section on the line 5-5 of Fig. 4.

Referring to the drawing more particularly by reference numerals, andnoting particularly Figs. 4 and 5, there are shown in assembled relationa journal box 9, one journal iii of a pair of car wheels (not shown), ajournal brass Ii having handling portions l2, a journal wedge I3, and ajournal wiper I4 constructed in accordance with the teachings of thepresent invention.

The journal wiper I4 preferably comprises a central fiatportion l5 andopposed side portions I6, i1 and I8, disposed according to theconfiguration shown in Figs. 1-3. There is a longitudinal opening I9 ineach of the portions II which extends into the respective portion I6.-Each of the portions l8 terminates in a square-cut wiping edge 20 whichwears in a self-sharpening action to conform to the journal l0.Extending from the central portion I5 is a lip 2i which is adapted toposition the wiper M. The journal wiper I4 is preferably constructed ofa singlepiece of sheet metal of light gauge, the exact configuration being determined by the cross-section of the journal brass and journalwedge (Fig. 5).

The operative disposition of the journal wiper I4 is clear from Figs. 4and 5. The journal wiper i4 is disposed between'the journal brass II andthe journal wedge IS, the openings i9 extending around the handlingprojections [2. The wiping edges 20 engage the journal l0.

With the wiper I4 disposed between the journal brass i I and the journalwedge l3, the wiping edges 20 engage the journal i0 along substantiallythe full longitudinal extent thereof firmly enough to prevent thepassage of sand, grit, waste,

and the like, yet lightly enough to prevent scraping all of thelubricant therefrom. Since the wiper I4 is of a resilient metal, theedges 20 will resiliently engage the journal ill, the moving contact ofthe metal on metal preventing the formation of a seal which wouldprohibit the passage of oil and which would dry out the journal III. Theresilient engagement of the wiper It with the journal l0 permits theedges 20 to remain in engagement therewith even during serious relativemovement between the journal l0 and the journal brass II, which toooften occurs when thecars the waste 22 to be moved between the Journalbrass l I and the journal l0.

It is apparent, therefore, that the Journal wiper i4 is of simple yetvery eilective construction, and that it is adapted to fulfill all ofthe objects and advantages sought therefor.

It is to be understood that the foregoing description and accompanyingdrawing have been given by way or illustration and example and not forpurposes of limitation, the invention being limited only by the claimwhich follows.

What is claimed is:

A Journal wiper comprising an integral body formed of resilient sheetmetal, and means for maintaining said body in operative disposition toprevent lateral displacement, said maintaining means comprising anupturned lip adapted to lie between an end of a journal wedge and ashoulder of a Journal brass, said body including a central portionadapted to be disposed between a Journal wedge and a journal brass. andside portions extending at an angle from the central portion insymmetrical relation adapted to extend around and below the Journalbrass, each side portion including a lower segment free of I engagementwith the brass, the lower segments being disposed in convergingrelationship and terminating in tree straight edges, said lower segmentsbeing of substantial width to block the passage of waste or the likethereover, said tree 10 straight edges being spaced apart a lesserdistance than the chord length of that portion or a Journal adapted tobe contacted, said tree edges being adapted to contact resiliently andcontinuously a journal throughout substantially the longill tudinalextent thereof to prevent the passage oi. dirt, sand, and the like, saidresilient contact or the free edges providingmeans to maintain the edgesin rounded cross-section in the rocking action oi the wedge and journalbrass during movement of the car, whereby a sled runner contact ismaintained which prevents scraping of all oil from the journal.
